Crisis, as an exogenous shock, can significantly change the basic premise of organizational operation. The application of digital technology not only helps to cope with the crisis, but also gives birth to new types of innovation. Based on the theoretical perspective of crisis management and organizational ambiguity, two dimensions of digital innovation are analyzed and established, including innovation drive (Sense of urgency and Sense of ambition) and innovation focus (exploitation and exploration). On this basis, the classification framework of digital innovation mode is constructed. Four innovation models and their characteristics are explained and discussed, combined with organizational digital innovation cases during the COVID-19 crisis to illustrate how and why they lead to digital innovation in the context of the crisis.
